Operation
The IC485S / GB / EU supports 4 kinds of functions in 6 types of configurations.
Point-to-Point
Point-to-Point configuration means two devices that locate different places can be linked
together to communicate through a couple of IC485S / GB / EU devices.
If the PC1 is a DTE device, then the Device A SW1 should be set to DCE. If the PC1 is a
DCE device, the the Device A SW1 should be set to DTE. The switch setting method for
the Device B is identical to Device A’s.
